A Study of Relationships Between University Interscholastic League Participation and Selected School Characteristics

A Study of Relationships Between University Interscholastic League Participation and Selected School Characteristics

Date: August 1998
Creator: Wisdom-Walters, Patricia Bowen
Description: The problem of this study was to determine whether differences exist between elementary and middle school campuses that participate in University Interscholastic League (UIL) academic activities and similar campuses that do not participate. The Texas Education Agency Academic Excellence Indicator System (AEIS) furnished data from 1993 through 1997 for this ex post facto comparative research. Using all Texas Assessment of Academic Skills (TAAS) scores for grades 3 through 8, economically disadvantaged population data, attendance rates and campus accountability ratings, 12 hypotheses and 4 research questions were addressed.

Synthesis and Study of Engineered Heterogenous Polymer Gels

Synthesis and Study of Engineered Heterogenous Polymer Gels

Date: August 1998
Creator: Chen, Yuanye
Description: This dissertation studies physical properties and technological applications of engineered heterogenous polymer gels. Such gels are synthesized based on modulation of gel chemical nature in space. The shape memory gels have been developed in this study by using the modulated gel technology. At room temperature, they form a straight line. As the temperature is increased, they spontaneously bend or curl into a predetermined shape such as a letter of the alphabet, a numerical number, a spiral, a square, or a fish. The shape changes are reversible. The heterogenous structures have been also obtained on the gel surface. The central idea is to cover a dehydrated gel surface with a patterned mask, then to sputter-deposit a gold film onto it. After removing the mask, a gold pattern is left on the gel surface. Periodical surface array can serve as gratings to diffract light. The grating constant can be continuously changed by the external environmental stimuli such as temperature and electric field. Several applications of gels with periodic surface arrays as sensors for measuring gel swelling ratio, internal strain under an uniaxial stress, and shear modulus have been demonstrated. The porous NIPA gels have been synthesized by suspension technique. Microstructures of newly ...

Team Compensation Systems: a Survey and Analysis

Team Compensation Systems: a Survey and Analysis

Date: August 1998
Creator: Zobal, Cheryl
Description: The purpose of this project was to examine team compensation systems and to evaluate the impact of their critical elements--level (what to motivate), compensation mixture (what rewards motivate), and employee perceptions (how to motivate)--on team effectiveness. Twenty-three organizations, 108 teams, and 769 team members participated in this study. Project results found that teams that utilized team level rewards, especially when associated with a complete compensation mixture, had significantly higher team effectiveness scores compared to teams that utilized only individual level rewards. With respect to employee perceptions, results found that: (a) perceptions of system understanding, measure controllability, pay-for-performance, and payout frequency, particularly, were significant components of employee compensation system satisfaction; and (b) employee compensation system satisfaction and perceptions of compensation system effectiveness were significantly related.

The Theme of Isolation in Selected Short Fiction of Kate Chopin, Katherine Anne Porter, and Eudora Welty

The Theme of Isolation in Selected Short Fiction of Kate Chopin, Katherine Anne Porter, and Eudora Welty

Date: August 1998
Creator: Arima, Hiroko, 1959-
Description: "The Theme of Isolation in Selected Short Fiction of Kate Chopin, Katherine Anne Porter, and Eudora Welty" examines certain prototypical natures of isolation as recurrent and underlying themes in selected short fiction of Chopin, Porter, and Welty. Despite the differing backgrounds of the three Southern women writers, and despite the variety of issues they treat, the theme of isolation permeates most of their short fiction. I categorize and analyze their short stories by the nature and the treatment of the varieties of isolation. The analysis and comparison of their short stories from this particular perspective enables readers to link the three writers and to acknowledge their artistic talent and grasp of human psychology and situations.

Underwater Optical Properties of Lake Texoma (Oklahoma-Texas) Using Secchi Disk, Submarine Photometer, and High-Resolution Spectroscopy

Underwater Optical Properties of Lake Texoma (Oklahoma-Texas) Using Secchi Disk, Submarine Photometer, and High-Resolution Spectroscopy

Date: August 1998
Creator: Rolbiecki, David A. (David Alan)
Description: The underwater optical climate of Lake Texoma was measured at eleven fixed stations from August 1996 to August 1997. Secchi transparency and submarine photometry characterized seasonal and spatial values of secchi depth (SD), vertical attenuation coefficient (η''), and depth of euphotic zone (Zeu). Indices of Zeu:SD and η'' × SD were compared with universally applied values derived from inland and coastal waters. Turbidity explained 76% of the variation (p = 0.0001) of η'' among water quality parameters, including chlorophyll-α. Using a spectroradiometer, spectral signatures of chlorophyll-α and turbidity were located. Stations with low turbidity exhibited a distinct green reflectance peak around 590-610 nanometers, indicating presence of chlorophyll-α. Stations with high turbidity exhibited a reflectance peak shift towards the red spectrum, making it difficult to detect the chlorophyll signature. Derivative analysis of the reflectance signal at 590-610, and 720-780 nanometers allowed discrimination of this chlorophyll signature from those of turbidity (0.66 ≤ r^2 ≤ 0.99).

Unearthing the Spiritual Message in Edward Abbey's Desert Solitaire

Unearthing the Spiritual Message in Edward Abbey's Desert Solitaire

Date: August 1998
Creator: Jacobs, Pamela
Description: Unearthing Edward Abbey's spiritual philosophy is not an easy task. One must sift through Abbey's humor, sort through Cactus Ed's flamboyant character, look under the veneer of this character, and beyond Abbey's overt objective of convincing readers to defy the destruction of wilderness, and only then does the spiritual philosophy of Abbey become visible. To understand his perception of spirituality, one must define what constitutes a mystic and determine what American theological philosophies mystics tend to adopt. Once these are defined, one can apply those principles to Abbey's Desert Solitaire, and determine that Abbey is a nature mystic who adheres to the ecocentric based immanence theology. This theology is contrary to the Judeo-Christian based emanation theology which supports anthropocentricism and resourcism.

Use of Stufflebeam's CIPP Model to Assess a Change Effort in a Division of a University Library

Use of Stufflebeam's CIPP Model to Assess a Change Effort in a Division of a University Library

Date: August 1998
Creator: Dworaczyk, William J.
Description: Reorganization efforts within colleges and universities are increasingly considered as institutions look for ways to streamline operations for financial cost savings or competitive advantage. The purpose of this study was to assess a particular change effort in a university library which took place between August, 1996 and July, 1997. A team was formed to manage the change effort, and an outside consultant was hired to facilitate the process and guide the team. Stufflebeam's evaluation model was used as a conceptual framework to evaluate the entire process which included a particular change management model brought in by the consultant. The entire change effort was described by the author as a participating member of the team and assessed by gathering feedback from team members, library staff members affected by the effort, and members of the library administration.

Use of tRNA Gene Probes to Identify Polymorphic Loci in the Bovine Genome

Use of tRNA Gene Probes to Identify Polymorphic Loci in the Bovine Genome

Date: August 1998
Creator: Shariat, Parvaneh
Description: A 30-mer oligonucleotide probe encoding the "A box" and anticodon loop regions of a human glycine tRNA gene was used to isolate a 581bp DNA fragment from a bovine genomic DNA library. Although the cross-hybridizing segment of DNA was found not to encode any tRNA gene or pseudogene, a region with homology to the "C-element" of the "BOV-tA" type Alulike artiodactyl retroposons was identified. This cross-hybridization was determined to be the result of conserved RNA polymerase III promoter elements in the probe portion of the tRNA gene and these repetitive elements. A microsatellite repeat (TC) was also found associated with this element. Future screening for bovine tRNA genes will require the use of a) longer probes and higher stringency hybridization conditions or b) the simultaneous screening with probes from the 5' and 3' ends of the gene which avoid the conserved Pol III promoter boxes.

Validation of the Expanded McCarron-Dial System for Diagnosis of Neuropsychological Dysfunction in Adults

Validation of the Expanded McCarron-Dial System for Diagnosis of Neuropsychological Dysfunction in Adults

Date: August 1998
Creator: Colaluca, Beth
Description: The McCarron-Dial System (MDS) has successfully predicted vocational and independent living outcomes with neuropsychologically disabled individuals receiving rehabilitation services. In addition, preliminary validation studies suggest that the abbreviated MDS is useful for clinical neuropsychological diagnosis. The present study represents part of an ongoing research project aimed at validating the expanded version of the MDS for diagnosis of neuropsychological dysfunction. Specifically, it was hypothesized that the expanded MDS would be able to accurately discriminate between brain-damaged and non-brain-damaged individuals. Accurate diagnosis facilitates rehabilitation efforts for individuals with neuropsychological disabilities and the data profile provided by the expanded version of the MDS can consequently form the basis from which more complete individual treatment and rehabilitation plans can be conceptualized.
